"Pharmaceutical grade fish oil" is defined as purified, winterized, and deodorized fatty oil obtained from fish. Therefore, this term is used to describe the quality of fish oil, encompassing purity (minimal detected contaminants/toxins such as heavy metals, PCBs, and dioxins), freshness (free of oxidative rancidity), and potency (amount of omega-3s contained). Because there are no pharmaceutical grade standards for fish oil in the United States, Nordic Naturals evaluates the fish oil used in its products by the stringent European Pharmacopoeia Standard.
The fish oil used in all Nordic Naturals products is third-party tested to verify that it surpasses these strict standards for purity and freshness, and that it reaches the level of potency claimed on the label. Our certificates of analysis are available upon request. To further ensure the quality of Nordic Naturals fish oil, we produce our fish oil in the triglyceride form, unlike many ethyl ester fish oils on the market today. True triglyceride form ensures that your body recognizes and absorbs the omega-3 essential fatty acids it needs for optimal health, and that your results are consistent. For more information about the triglyceride form, see question below.
